Narrowing searches based on url, author, date, and other attributes is also possible.
For instance, the query
[ Conan sourcename:Poynter ]
restricts searches for "Conan" to items from the blog "Poynter".
Examples of other operators follow:

• sourceurl:http://www.huffingtonpost.com/

items from the blog http://www.huffingtonpost.com/

• author:"Rupert Murdoch"

items by author "Rupert Murdoch"

• sourcename:"E-Media Tidbits"

items from blogs with "E-Media Tidbits" in the name

• title:substantiated

items with "substantiated" in the title

• date:01/28/10

items that appeared on 01/28/10

• body:"sharp gains"

items with "sharp gains" in the body

• date:[01/28/10 TO 02/04/10]

items appearing between 01/28/10 and 02/04/10

• link:http://www.apple.com/pr/library/2010/01/27ipad.html

items linking to http://www.apple.com/pr/library/2010/01/27ipad.html

Note: all operators that take urls will accept simple domain names, which match any item at that domain, or complete item urls.

Rethinking TV news, Part I: What's broken, what's possible
— Most TV news sucks. But I don't want to dwell on that. — I'd like to see TV news be reinvented, yet I'm astounded so little innovation is occurring in the medium. That could be because TV news is still in better financial shape than print.

The almost-post mortem for Patch
— David Carr all but writes the obit for Patch today. One could quibble and say it's not quite dead, that Aol plans partnerships for the ill-fated ganglion of local sites. Fine, but it's still not wrong to look back and ask what went wrong.
